WebJun 14, 2024 · I am trying to compute the information length or distance induced by the Fisher information metric on the statistical manifold of the categorical distribution (the interior of the n-dimensional simplex). I have checked each part of my computation several times. However, the result I obtain is dependent on my original choice of chart. WebFisher information [19]). While the relation between Fisher metric and Markovianity has been previously partially ana-lyzed [20] here we characterize it completely.
